WebApr 19, 2024 · Chi-Squared is a continuous probability distribution. It is also used heavily in the statistical inference. We utilise chi-squared distribution when we are interested in confidence intervals and their standard deviation. Just like student-t distribution, the chi-squared distribution is also closely related to the standard normal distribution. WebN – 2 1 minus the squared r value, divided by N – 2.
